Studies on a Hib-tetanus toxoid conjugate vaccine: effects of co-administered tetanus toxoid vaccine, of administration route and of combined administration with an inactivated polio vaccine.

A freeze-dried tetanus toxoid (T) conjugated Haemophilus influenzae type b (Hib) vaccine, was reconstituted in either diphtheria toxoid (D), DT or a combined DT and inactivated polio vaccine (IPV), and administered in an open randomized trial either intramuscularly (i.m. ) or subcutaneously (s.

Safety and immunogenicity of a combined diphtheria-tetanus-acellular pertussis-inactivated polio vaccine-Haemophilus influenzae type b vaccine administered at 2-4-6-13 or 3-5-12 months of age.

Methods: In an open randomized study we compared the safety and immunogenicity of two schedules for priming and booster vaccinations of infants. A pentavalent combination vaccine, including a lyophilized Haemophilus influenzae type b-tetanus toxoid conjugate vaccine reconstituted with a liquid diphtheria, tetanus, acellular pertussis (pertussis toxoid and filamentous hemagglutinin) and inactivated polio vaccine (DTaP-IPV/Act-HIB; Pasteur Mérieux Connaught, Lyon, France) was administered to 236 Swedish infants either at 2, 4 and 6 months or at 3 and 5 months, and a booster dose was administered 7 months after the last primary dose. Adverse events were monitored by diaries for 3 days after each vaccination and by questions at the ensuing visits.

Pain relief during delivery. An evaluation of conventional methods.

The study evaluates the effect of conventional obstetric analgesia on 544 parturients and their newborn infants. The parturients' pain situation was evaluated with respect to both the effect of pain relief given, and the total pain experience in the first and second stage. This gave a more correct view of the parturients' pain situation and effectiveness of the analgesic procedures that if one or the other estimation was used separately.

Pain relief in labor by transcutaneous electrical nerve stimulation. A prospective matched study.

The study evaluated transcutaneous electrical nerve stimulation (TNS) for pain relief in labor, used in parallel with conventional methods. The investigation comprised 566 vaginally delivered women, 283 of whom were given TNS. Pain relief was evaluated with a questionnaire which the women answered shortly after delivery.

Impedance cardiographic assessment of symptomatic patent ductus arteriosus.

A modified impedence cardiographic technique was developed using a tetrapolar apnea monitor and minicomputer system. Evaluation of this technique in premature infants with and without symptomatic patent ductus arteriosus indicates that the magnitude of the cardiac-related deflection in the impedance signal is useful in the assessment of ductus shunting. Since the infant under study is involved only by the attachment of two double electrodes to the thorax, continuous assessment of ductur shunting is possible without disturbing routine care.
